TYPE CASTING AND FiNiSHiNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 392,710, dated November13, 1 888.

Serial No. 280.226. (No model.)

To all whom it may concern:

Be it known that we, HENRY EARTH and Enns'r Lrnrzn, both citizens of theUnited States, and both residing at the city of Cin- 5 cinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Type Casting and Finishing Machines, of which thefollowing is a specification.

This invention relates to type casting and finishing machines in whichthe type is cast in a horizontal position, and,after the mold-coveringslide is moved to one side,so as open the mold, pushed up out of themold, and then,by 1 the returning mold-covering slide, pushedhorizontally to a vertical channel, pushed down into this channel,andthen out ofit onto a horizontal rule, and in which machines the type,after being pushed up out of the mold and while in a horizontal positionor moving horizontally, is shaved at its upper and lower surfaces andseparated from the jet.

The present invention may be regarded as improvements on the machine forwhich Letters Patent No. 376,765 were granted to us on or about the 24thday of January, 1888. EX- cept the improvements within described, andpointed out by the claims, all parts of the frame-work and mechanism aresubstantially the same in this improved machine as in our said priordevice.

The objects of our invention are, first, to provide means for limitingpositively the movement of the mold-covering slide and for adjusting thelimit of this movement accurately and conveniently; second, to supplythe mold-covering slide with a looking or bolting device to act when themold is closed and to cause the faces of the stationary and the slid- ,0ing parts of the mold which come in contact with the matrix to be in oneplane even when the moldcovering slide shall have worn a lit- He play inits guides; third, to prevent shavings produced by the uppershaving-knife from adhering to the mold-covering slide and from beingtaken along by the same, so as to come between the faces of mold andmatrix; fourth, to design an improved mechanism for holding the typewhile being transferred from the mold to the said vertical channel andwhile it is shaved and freed from its jet; and, fifth, to construct animproved matrixholding device which secures a perfect contact betweenmatrix and mold. WVe attain these objects by the devices illustrated inthe accompanying drawings, in which- Figure 1 represents a frontelevation of a portion of the machine; Fig. 2,atop View of aportion ofthe machine; Fig. 3, a sectional detail view showing theleft end of themold-covering 6o 7 slide and parts of the device for limiting themovement of the same and for adjusting the limit of its movement; Fig.4., a detail View showing the end of the matrix-slide, which is brokenoff in Fig. 2 by the marginal line of the drawings; Fig. 5, alongitudinal section of a part of the machine through the center of themold about the line X X, Fig. 14.

Similar numerals or letters refer to similar parts throughout theseveral figures, and all parts which are the same in these improvementsas in our prior machine (described and illustrated in the specificationof Patent N 0. 375,765, dated January 24, 1888) are repre sented by thesame characters in this as in the specification of our said priorpatent.

Referring to the drawings, the mold, Figs. 5 and 1 1-, into which themetal is forced by a pump through the nipple 31 and the apron 45, iscomposed of stationary and of movable parts. The stationary partsconsist of the side members or checks, 61 and 65, Fig. 5, which arepermanently attached to the integral baseplate 68 and supported and heldby the moldbeam 5, which is a part of the stationary framework of themachine. The jet-pieces 66 and 67, Fig. 17,'also partly visible in Fig.2, may be considered as parts of the cheeks 6i and 65. For practicalreasons they are made separate] y and attached to the cheeks by means ofthe bolts and 71. The part 267 does not belong to the mold proper. It isfastened to the base-plate 63. It serves for supporting the shavingknife99, and has a gutter through which the shavings coming from theshavingknives are conducted away. The movable parts of the mold are thebody-piece 68, the sliding cover 69, and the matrix 181.

The body-piece 68 forms the bottom of the mold and serves also to pushthe type up out of the mold. It is fixed to the vertical sliding bar74., passes through a rectangular hole in the base-plate 63 of the mold,and fits accurately between the cheeks 61 and 65 and the jet-pieces 66and 67. The top surface of the body-piece 68 has precisely the form ofthe type with its j ct. The slidingbar 7 1-,t0 which the body-pieces 68of the mold is attached, is guided in a groove that is planed in themold beam 5 and closed by the lid 76, Fig. 1 1. The parts 165 and 166,which appear in Fig. 11 in section, are wedges passing through holes inthe sliding bar 74, and serve for limiting the motion of the slidingbar, and, consequently, that of the body-piece of the mold, as also toadjust the limits of said motion in such a manner that the top surfaceof the body-piece is exactly flush with the top surface of the, cheeks64 and 65 when the body-piece is in its highest position, and so thatthe mold has the required depth when the body-piece occupies its lowestposition.

The mold-cover 69 is a great deal longer than the stationary parts ofthe mold and slides on the top surface of themold-beam 5 and on the topsurfaces of the stationary parts of the mold, which surfaces are workedaccurately to one level. Sidewise the slide 69 is guided between theplates 77 and 78, Figs. 1 and 2, which are bolted to the sides of themold-beam. The

parts which are attached to the slide 69 and the functions of the samewe will describe hereinafter.

The slide 69 closes the mold on top during the time the metal is forcedinto the mold. It moves toward the left and opens the mold after thetype is sufficiently cooled off and solidified, stops in its extremeleft position and leaves the mold open until the type is pushed up outof the mold,and moves then toward the right and pushes the type alonguntil the latter will be exactly over the vertical channel 261, intowhich the type is pushed and in which it is grooved and dressed.

The matrix 181, Fig. 1 1-, shuts the mold in front while the type isformed, and it is withdrawn before the type is pushed out of the mold bythe body-piece 68. The arrangement of the parts which support and holdthe matrix we will also describe later on.

In Fig. 14 the mold is shown closed and the type 262 in the position itoccupies just after being formed.

In Figs. 1, 2, and 5 the slide 69 is in its extreme left position andthe mold opened.

In Fig. 5 the type 262 appears in the position which it occupies justafter being pushed up out of the mold, and the vertical channel 261 isshown as being filled with types.

The mechanisms for operating the mold-covering slide 69, the sliding bar7 1, with the bodypiece 68 of the mold, and the lever 188, Fig. 14, ofthe matrix motion, as also the dressing apparatus and the device bywhich the types are pushed down into the vertical channel 261 of thegrooving and dressing apparatus, are the same in this improved machineas in our said prior device. They were fully described in thespecification of Patent No. 876,7 65,and as they are not referred to inthe present improvements it will notbe necessary to describe themherein.

The first object of our improvements prcsented herein is to supply theslide 69 with an easily-adjustable device for positively limiting themotion of the same in one direction. It is very important that when themold-covering slide arrives at the right extremity of its stroke thetype be accurate] y over the perpendicular channel 261. This position ofthe type depends upon the end position of the slide 69, and experiencehas taught us that on account of unavoidable wear in the joints of themoving parts and for other reasons the slide 69 will not stop preciselyat the same point after every movement without such a device.

In order to attain our object we provide the slide 69 with the stud 245,Figs. 1, 2, and 3, which is screwed into the end of the slide andterminates in a screw. cross-head 264 is fitted in a manner which prevents it from swiveling on the stud,but permits to adjust itlongitudinally. The adjustment of the crosshead is accomplished by meansof the nut 21-7 engaging the screw at the end of the stud. In order toprevent the cross-head from swiveling on the stud,the part of the latteron which the cross-head is fitted is filed flat To this stud the IIO ontop and a suitable gib is inserted in the cross-head. Between thecross-head 246 and the nut 24.7 a washer is placed. The crosshead isprovided with a set-screw, by means of which it can be tightened to thestud. The mold -covering slide 69 moving toward the right will bestopped when the cross-head 246 touches the plates 77 and 78, Figs. 1and 2, which are bolted to the sides of the mold-beam 5 and betweenwhich the slide 69 is guided,and if the cross-head is correctly adjustedthe slide 69, and with it the type, will occupy the desired position. Itmay be mentioned that the crosshead, fastened by the set-screw in theproper place,is alone sufficient to cause the mold-covering slide tostop at the correct point, and that the screw and the nut at the end ofthe stud serve to do the adjusting of the crosshead conveniently.

The second object of our improvements-to cause the faces of the cheeksand of coveringslide of the mold on which the matrix rests to beprecisely in one plane when the mold is closed, and to prevent herebythe metal from leaking between matrix and mold-we attain by thefollowing locking or bolting device: The plate 234 (shown in detail inFigs. 6 and 7) terminates in a fork and is bolted to the top of theslide. 69 at the right end of the latter, so that the fork projectstoward the right. Another plate,233, drawn in detail in Figs. 8 and 9,is provided with a projection or tongue corresponding in form and sizewith the fork of plate 234. This plate is bolted to the stationaryframing of the machine at such a place and in such aposition that whenthe mold is closed and the faces of the said parts of the mold are inproper position the said tongue fits tightly in the fork of plate 23st.The tongue and the opening in the fork are made taper, so that the tightfit of these two pieces only takes place when the mold is entirelyclosed. In order to provide foran adjustment of the tongue in relationto the fork, the plate 233 has a groove planed in its bottom face. Thepart230 oftheframingon which the plate 233 bears, is prepared with acorresponding feather, and the bolt holes in plate 233 are made a littlelarger than the bolts for holding it down, so that the plate 233 can bemoved in a straight line by means of the setscrew 236,which works thestationary nut 235, Figs. 1,2, and 5. It is evidentthat the same resultwould be accomplished if the slide 69 were constructed with a tongue anda fork were ap plied to the stationary framing; and that a taper holecould be substituted for the fork if a taper pin were used instead ofthe tongue; or that one of these parts could be made with severalprojections and the other with an equal number of correspondingindentations. In our prior device we arrived at this object by closelyfitting the slide 69 between its guide; but we found such close fittingto be difficult and troublesome to maintain.

In our prior device a small knife was attached to the mold'coveringslide 69, near the right extremity of the latter, for the purpose ofshaving(or"rubbingthetechnicaltermused by type-founders) the upper sideof the type while the same was still lying in the mold and while theslide 69 was moving toward the left, so as to open the mold. Thisarrangement presented the trouble that often shavings produced by theknife adhered to the slide and the faces of the cheeks and came, whenafterward the mold was closed again, between mold and matrix and causedleakage. The shavings sometimes found their way under the mold-coveringslide and lifted it up. To obvi ate these troubles is the third objectof our improvements, and we attain it by the following arrangement: VVeremove the upper rubbing-knife from the mold-covering slide andsubstitute for it the stationary knife 258, Figs. 1, 2, 10, and 17,which is adjustably attached to the plate 257. This plate is firmlysecured to the part 267 of the moldbase, and has a proj eetion, 265,Fig. 10, which is so fitted that when its lower side rests upon the part267 its upper sideis precisely in one level with the top surface of themold. In order to adjust the knife 258 to heigh t,a finished type isplaced between the projection 265 of the plate 257 and the knife; thenthe knife pressed down gently and fastened to the plate 257 by means ofa screw. Between the knife 258 and that part of the mold on which thematrix rests when the mold is closed a wiper, 256, made of bristles,cloth, felt, leather,or asimilar material and attached to a'sheet-ironholder, is arranged so that the end of the wiper touches the mold. Thewiper-holder is fastened to that part of the framing which forms theguide for the matrix-slide and to which the side and head bearings forthe matrix are applied. The wiper 256 and its holder 255 have a notch,Fig. 18,just large enough to allow the part of the type which was formedin the matrix to pass freely. The mold is also provided with the bottomshaving-knife, 99, and the breaker 100,Fig. 17, which are the same inthis machine as in our said prior device. The typeis now in thisimproved arrangement shaved on top and bottom side and freed from itsjet, while the moldcovering slide moves toward the right and pushes thetype from the place where it was pushed up out of the mold to thevertical channel, into which it is delivered afterward to be grooved anddressed. This arrangement successfully preventsshavingsfrom arriving atthe left side of the wiper.

The fourth object of our improvements was suggested to us by the factthat thin types were compressed sidewise in our prior machine whilebeing transferred from the mold to the said vertical channel. From thisfact we learned that thin types ought not to be held with the samehorizontally-directed pressure as thick ones require while passing thebreaker, because the pressure acts in thinner types upon a smallersurface than in thicker ones, and the types, being still warm, areeasily compressed. Very thin type can bear no side pressure at allwithout being deformed. For

nates.

tunately the jet of a thin type requires but a small force in order tobe removed, and a vertical pressure is sufficient to hold the typeduring this operation. With these points in view we have designed thefollowing devices for holding the type while it is transferred from theplace where it is pushed up out of the mold to the vertical channel ofthe grooving and dressing apparatus and while it passes theshaving-knives and the breaker. The mold-covering slide is provided witha cylindrical hole near its right end, in which the piston 88 is fitted,Fig. 5. The lower part of the hole is slotted through to the right endface of the slide, and at the lower end of the piston 88 a littlefeather is worked on, which projects into the slot and prevents thepiston from turning. A plate, a. a trifle thinner than the thickness ofthe bodies of the type and about as wide as the bodies are high, isscrewed to the feather on the piston. The piston 88 is partly hollow,and in its interior is placed a spring, which rests on a small plate,105, screwed to the bottom surface of the slide 69 and has the tendencyto push the piston up. Near its upper end two trunnion-like pins,90,projecting forward and backward, are applied to the piston 88. The twopins 90 are provided for the fork to act upon,in which the right arm ofthe three-armed lever 238 termi- The stand 94, which is bolted to theslide 69, serves as a fulcrum-support for the three-armed lever 238. Thespring-rod 242 is pivoted to the upwardly-directed arm of the lever 238and is guided in a hole of the post 244, which is secured to themold-covering slide 69, Figs. 1 and 2. The spring 243, which is slippedon rod 242, rests against the post 244 and forces the upright arm of thelever 238 toward the right, so that the fork of the right horizontal armpresses the cylinder 88, with the plate a, downwardly. Theadjusting-screw 239 is tapped in the right arm of lever 238, has ajam-nut to prevent it from being jarred loose, and limits the downwardmovement of the cylinder 88 when its point strikes the head of the bolt,which holds the plate 234 to the moldeovering slide 69. The tail of thethird arm of lever 238 acts asa camtrack and engages the stationaryroller 241 when the mold-covering slide 69 arrives at the left extremityof its stroke, whereby the cylinder 88, with the plate a, is releasedfrom the pressure of the spring 243. The roller 241 is pivoted to theangular piece 240, Figs. 1 and 2, which is bolted to the guide-plate 78of the slide 69 in such a manner as to provide a vertical adjustment ofthe roller. When the moldcovering slide 69 stops in its extreme leftposition, (see Fig. 5,) the.plate a is right above the type in the mold.After the type has been pushed up out of the mold and the body-piece 68is exactly flush with the top surface of the mold, the slide 69 startsto move toward the right, touches the type, and pushes it along. Beforethe type reaches one of the knives the cam-track on the left arm of thelever 238 leaves the roller 241 and the spring 243 comes into action andby means of the lever 238 and the cylinder, with the plate a, pressesthe type down. This arrangement is perfectly sufficient to hold thintypes, which would not stand being held sidewise in passing theshaving-knives and the breaker. When the slide 69 has arrived at itsextreme right position and stops and the type is exactly over thevertical channel 261 of the grooving and dressing apparatus, the rod 103will be set in motion and the setscrew 104 in the upperhorizontally-bent part of this rod will strike the piston 88 and theplate a will push the typeinto the vertical channel 261 between theplates 101 and 102 to be grooved and dressed. WVhen the mold-coveringslide 69 is returning toward theleft, the set-screw 239 in the righthorizontal arm of the lever 238 and the spring in the hollow cylinder88, which lifts the cylinder up, prevent the lower face of the plate afrom touching the face of the mold.

For thick types, which require to be held by a larger force whilepassing the breaker, we use the parts which we are going to describe nowalone or in combination with the foregoing device.

The sliding bar 237, Figs. 2 and 5, is guided in the case 230 andarranged in one line with the mold-covering slide 69,- so that its leftend faces the right end of the latter and its lower or bottom side liesin the horizontal plane in which the top surface of the mold and thebottom surface of the slide 69 lie. It is made hollow for the greaterpart of its length. The rod 232 is centrally attached to it, extendsbeyond the right end of the same, passes a hole in the plate 231, bywhich the guiding-case 230 is closed, and terminates in a screw.Aspring, which is slipped on the rod 232 and rests against the plate231, forces the sliding bar 237 against the mold-covering slide 69. Bymeans of two nuts, which are placed at the right extremity of the rod232, the left-end position of the sliding bar 237 is so adjusted thatwhen the mold-covering slide arrives at its extreme left position thetype can be freely lifted up out of the mold, and will then be betweenthe left-end surface of the sliding bar 237 and the right-endfaee of themold-covering slide 69, as shown in Fig. 5. Now, when the mold coveringslide 69 will move toward the right, the type will be held, by Virtue ofthe spring on rod 232, between the opposite end faces of the slides 69and 237.

Very small types must be cast quickly and in a comparatively hot mold.They are very easily damaged in the state in which they are lifted outof the mold, and the pressure with which they are held between the endfaces of the slides 69 and 237 must be reduced to a minimum-that is tosay, the pressure must be just sufficient to hold the type, but notgreater. Inv order to regulate this pressure,we apply the block 268,Figs. 19 and 20, to the sliding bar 237. This part has side flanges forthe bar 237 to fit between, and is secured to the bar by means ofascrew. The hole through which the screw passes is made a little largerthan the screw, which allows to so adjust the position of the block thatwhen its projecting point touches the mold-covering slide the width ofthe space between the opposite end faces of the slides 69 and 237 isequal to the thickness of the type bodywise. hen the type con fined inthis space and moving forward meets the breaker, there is a tendency toturn the type above a vertical axis, but the confinement prevents suchmotion taking place. At the same time the type is pressed by a couple offorces called into action by the resistance of the breaker against theend surfaces of the slides, and the friction due to this pressureprevents the type from moving longitudinally. In this manner thepressure by which the type is held horizontally regulates itselfaccording to the force required to break off the jet. When it isrequired to hold thin types by a vertical pressure only, or when heavytypes are wanted to be held with the whole force of the spring in thesliding bar 237, the block 268 need not be taken off, but only moved alittlein the first case toward the left and in the second case towardthe right.

For certain types we find it necessary to provide the end surface of thesliding bar 237 with a light spring, 269, Figs. 20 and 21, of justsufficient strength to hold the type. For this purpose we cut a shallowgroove perpendicularly into the end of the sliding bar 237. The lowerpart of this groove is rectangular. The upper part of the same has theform of a dovetail,and holds the spring 269. The groove could have beenmade just as well rectangular all through and the spring fastened to theslid ing bar by means of small countersunk screws. The spring 269 isslightly bent,so that its lower end projects a little over the end faceof the bar 237 5 but when force is applied to its lower end the springwill straighten and be even with the end surface of the sliding bar. Thegageblock 268 being so adjusted that the space be tween the opposite endfaces of the slides 69 and 237 is a trifle larger than the thickness ofthe types bodywise, the force by which the type is held horizontally islimited by the strength of the spring 269. Small types are often injuredby the percussion which takes place at the moment when the mold coveringslide 69 sets in motion the sliding bar 237. The spring 269 serves toprevent this. When heavier types are to be cast, for which the strengthof the little spring is insufficient to hold, this spring does not needto be removed. The gage 268 is only to be readj nsted, either so thatthe width of the space between the slides is equal to the thickness ofthe types bodywise, or so that the slide-block does not act at all.WVhen very thin types are required to be held by a vertical pressureonly, the gageblock 268 can be moved so much toward the left that thespring 269 does not touch the type.

The fifth object, which regards the improvement of the matrix-holdingdevice, was com mended to us by the difficulty which presented itself inour prior machine of maintaining the parallelism of the correspondingfaces of matrix and mold at the varying degrees of heat which thedifferent parts of the machine obtain at different times. Our object isto prvide an arrangement in which the face of the matrix willaccommodate itself to the front face of the mold. We attain this objectin the following construction: The slide 248, Figs. 1. 2, 4, 14, and 15,is operated by the lever 188 to and from the mold. The motion of thelever 188 is derived from asuitable cam and a spring precisely in thesame manner as in our prior device, Patent No. 376,765. The slide 248 isguided in the box 249, which may be considered as a part of the framingof the machine. The box 249 is made separately and dovetailed to themold-beam for convenience in making; but it could be cast in one piecewith the mold-beam just as well. The stud 266, Fig. 14, and the washerand nut on the same are intended to prevent the slide 248 from beinglifted up. The matrix 181 is held in the matrix-case 283, Figs. 12 and13, by means of the screw 264, and rests upon the matrixsupport 251,Figs. 14, 15, and 16. The latter is guided with its lower round parts ina hole of the slide 248, Fig. 14, and is constantly forced upwardly by aspring. The upper part or head of the matrix support forms a littleplatform, has a rectangular groove into which a part of the matrix-case263 projects,

and touches with one side an upward projec-- tion of the right flange ofthe guide-box 249, Figs. 2, 15, and 16, whereby the matrix-support isprevented from swiveling around its vertical axis. The said groove runsin the direction in which the slide 248 moves, but does not extendentirely across the top of the matrix-support, a rib being left at theside near the mold. The stationary plate 250, Figs. 1, 2, 14, and 15,which is secured by screws to the right flange of the guide-box 249,serves as a side-bearing for the matrix and determines the verticalposition of the same. The position of the matrix in relation to the moldcan be adjusted vertically, first, by fitting, say by filing, the upperside of the matrix-case; second, by fitting the bearing-surface on theright flange ofthe guiding-box 249, upon which the plate 250 rests, to aproper height, and, third, by fitting this bearing-surface a littlelower and inserting between it and the plate 250 a metal plate ofsuitable thickness. The wedge 253, Figs. 2, 15, and 16, serves asheadbearing for the matrix, as also for regulating the position of thematrix horizontally. It is placed under the plate 250 and fastened tothe upwardly projecting part of the right flange of the guiding-box 249,and can be adjusted by means of the screw 254. The slide 248 is providedwith a case,in which the stem 259 is guided, and which contains aspringthat pushes the stem in a direction toward the mold. The needle 252 isconnected with the stem 259 by means of a ball-and-socket joint, andimpinges with its conical point upon the matrixcase. It has such aninclination that when the slide 248 is in the position nearest to themold the matrix is forced, by virtue of the spring on stem 259, againstthe mold, up under the plate 250, and toward the wedge 253.

The strength of the springs on the matrix-support 251 and on the stem259, and thelocation of the point of impingement for the needle 252 onthe matrix-case 263, are so selected that the face of the matrix willaccommodate itself to the corresponding face of the mold even when, inconsequence of the heat, the lower face of the plate 250 should deviatea little from being rectangular to the face of the mold. The stem 259terminates in a screw, and is sup plied with a wing-nut and with thecollar 260.

The latter can be adjusted by means of the.

wing-nut, and has a set-screw with which it can be fastened to the stemin such a position that when the mold is closed by the matrix theclearance between the collar 260 and the slide 248 is about equal to theclearance be tween the downward projection of the matrixcase 263 and therib which closes the groove of the matrix-support 251. \Vhen the slide248 is returning, the matrix will keep in contact with the mold untilthe slide 248 touches the collar 260. At the same time the pressure withwhich the spring on stem 259 forces the needle 252 against thematrix-case will cease. Then the matrix will also be withdrawn, as therib on the matrix-support will act upon the downward projection of thematrix-case. lVhen the slide 248,and with itthe matrix, are completelywithdrawn, the latter may be casil y taken out and replacednamely, bydrawing a little on the stem 259 the needle 252 will leave the centerpunch-hole in the matrix-ease and can be movedout of the way, and thematrix being then near the front side of the plate 250 can beconveniently reached with a finger. When the slide 248 moves with thematrix toward the mold, the matrix will touch the mold before the slidearrives at its extreme position, and as it is then still rclcased fromthe pressure of the spring it will touch the mold without jar, exceptthat due to its own weight, and while the slide 248 is finishing itsmotion the spring 011 the stem 259 will be gradually compressed and thematrix held with force in its proper position.

Having thus described our invention, what we claim is- 1. In atype-casting machine, the combination, with the mold-covering slide andthe framing in which said slide is guided, of the stud 245, attached tothe end of said slide, and the cross-head 246, fitted adjustably to saidstud and adapted to limit, together with the framing, the movement ofthe mold-covering slide positively, substantially as set forth.

2. The combination, with a type-mold having stationary side members anda sliding cover and the stationary framing, of two parts,

one of which terminates in a fork and the other in a correspondingtongue, one of the said parts being fastened to the sliding cover of themold and the other to the stationary framing in such manner and positionthat when the mold is closed and the corresponding faces of the saidmold parts are exactly flush with each other the said tongue will fitclosely in the said fork, substantially as described and specified.

3. In a type casting and finishing machine, the combination,with atype-mold having stationary side members and a sliding cover, a matrix,and the stationary framing of the machine, of a stationary adjustableknife adapted for rubbing the upper side of the type while the same ismoved by the said sliding cover over the top surface of the stationaryparts of the mold, and a wiper fastened to a stationary part of themachine and adapted to remove shavings produced by the said rubbingknife which may adhere to the front face of the said sliding cover, andto prevent shavings from coming and adhering to those parts of themembers of the mold which come in contact with the matrix, substantiallyas set forth.

4. The combination,with the mold-covering slide, of the piston 88,guided in a hole of said mold-covering slide, the pushing-plate a onthis piston, the lever 238, fulcrumed to the said mold-covering slideand adapted to act upon the piston 88 downwardly,the spring 243, actingupon one arm of lever 238, the set-screw 239 for limiting the downwardposition of the said piston, and the stationary and adjustable roller241, engaging, when the said mold-covering slide arrives at its extremeleft position, the end of one of the arms of lever 238, and so releasingthe piston 88 from the downwardlydirected pressure caused by the actionof spring 243, substantially as and for the purpose set forth.

5. In a type-casting machine, the combination, with the mold coveringslide, of a sliding bar guided in a stationary casing placed a-linc withthe mold-covering slide and with its end facing the end of the latter, aspring adapted to move the said sliding bar in the direction toward themold-covering slide, and a stop for limiting the movement of the slidingbar in the direction in which the spring acts, the whole combinationbeing adapted to hold the type between the opposite end faces of themold-covering slide and the said sliding bar, substantially as setforth.

6. The combination,with the mold-covering slide, of a sliding bar guidedin a stationary casing and placed a-line with the mold-covering slide,so that its end faces the end of the latter, a spring adapted to movethe said sliding bar in the direction toward the mold-covering slide, astop for limiting the movement of the sliding bar in the direction inwhich the said spring acts, and a gage-block attached to the end of thesaid sliding bar and adapted to regulate the width of the space betweenthe end faces of the mold-covering slide and the said sliding bar,substantially as set forth.

7. The combination,with the mold-covering slide 69, of the sliding bar237, guided in a stationary casing placed a-line with the moldcoveringslide, so that the surfaces of the slides 69 and 237 face each other,and provided with the spring 269, attached to its end face, a springadapted to move the said sliding bar 237 in the direction toward themold-covering slide 69, and a gage-block, 268, attached to the end ofthe said sliding bar and adapted to adjust the width of the spacebetween the opposite end faces of the mold-covering slide 69 and thesliding bar 237, substantially as set forth.

8. The combination, with a type-mold and a matrix, of the matrix-case263, the slide 248, the matrix-support 251, guided in the slide 248 andpressed upwardly by a spring, the stationary plate 250, adapted todetermine the position of the matrix vertically, the Wedge 253, adaptedto adjust the position of the matrix horizontally, the spring-stem 259,guided in the slide 248, pressed by a spring in the direction toward themold and provided with an adjustable collar, 260, for limiting itsmovement, and the needle 252, connected with the spring-stem 259 by abalLand-socketjoint and adapted to impinge upon the matrix in suchoblique direction that thelatter will be pressed against the mold uponto the plate 250 and toward the wedge 253, substantially as shown anddescribed.
